COOLER.

Application filed June 3, 1913.

To all whom it may concern Be it known that I, GEORGE HERBERT BLAKE, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Coolers, of which the following is a specification.

My invention relates to the class of coolers in which submergence in water is the controlling principle.

My invention is applicable for cooling and keeping cool any substance which will bear submersion either because it is itself unafiected by contact with the water, or because it is confined in a container impervious to water; but, in order to more clearly define and illustrate the object of the invention, I will state that in my pres ent opinion it finds its highest utility in the cooling and keeping cool milk in bottles, in which connection I prefer to describe it.

My invention consists in a water vessel of any character, though, in its best form, of porous material, preferably of canvas or other like fabric permeable by water, said vessel having a bail for suspending it in a place conducive to surface evaporation, and a cover for said vessel, said cover carrying under it a suitable hanger for suspending the object to be cooled in the water, and having also such connection with the bail of the water vessel as will hold said cover in place and will guide and direct it accurately and conveniently in opening or lifting it to expose the confined object and enable it to be removed.

The accompanying drawings are referred to for a more complete understanding of the device and for illustration of the following detailed description.

Figure 1 is a perspective view of my cooler, broken away in part and showing the cover closed. Fig. 2 is a side elevation of the same, showing the cover lifted, the water containing vessel being in section. Fig, 3 is a bottom view of the cover, showing the hanger from which the article to be cooled is suspended.

1 is a vessel for containing water 2. This vessel may be of any suitable material, porous or non-porous. In its best form, however, it should be of porous material in order to take advantage of the well known Specification of Letters Patent.

cooling effect of rapid surface evaporation. Of all such porous material, I deem the best to be canvas or other like fabric, such as those bags are made of in which drinking Water is carried by prospectors and travelers in arid places. When the vessel 1 is made of such flexible porous material it is fitted at its top with a rigid mouth ring 3 to serve to keep its upper end distended and as a support for the cover which consists of a disk 4. Of course, when the vessel 1 is of rigid material, its own open top is its mouth and cover seat. To the top of the vessel 1 is fitted a bail 5 by which said vessel may be hung up in some place which will promote surface evaporation. It will be noted that the terminals of the bail extend'beneath the ring 3. The cover 4 has on its under side a hanger 6 of any suitable character adapted for suspending whatever object it is the in tention to cool. In the present case, I have illustrated this object as a milk-bottle 7 of well known type, and the hanger 6 is, therefore, a wire device adapted to readily receive and to engage the flanged head of the milk-bottle in such manner that said bottle is suspended from the cover and is submerged in the water 2 of the vessel 1.

In order to prevent and guard against any unintentional lateral displacement of the disk 4, and thereby to insure the protection of the interior of the cooler and the object to be cooled from the entrance or deposit of dust or other foreign matter, insects included, the cover and bail are made to engage in a manner which will hold the cover in its lace and yet will permit it to be lifted anc will guide and direct it in this op eration. This engagement must naturally assume a form which will prevent the horizontal or lateral displacement of the cover so that it cannot accidentally expose the mouth of the vessel 1, and at the same time will permit the vertical movement of said cover to open the vessels mouth when it is desired to reach its contents. A good engagement is that which I here show, namely,

rim-slots 8 in the cover slidably fitted upon the arms of the bail 5. The cover is provided with a hand knob 9 by which it may be conveniently lifted.

To place the milk-bottle 7 in the cooler, the cover 4 is lifted on the bail 5 and at the same time said bail is tilted. Its hanger 6 is thus conveniently exposed and brought into position which will enable the bottle 7 now introduced into the vessel 1, to slip its neck into the hanger on the cover. Then the cover is dropped back, and the bail straightened up. The milk-bottle now hangs from the cover and submerged in the water, and the vessel 1 may be hung out in the air. To reach the milk-bottle for use, the same operation is gone through with and the bottle is removed.

I laim 1. A cooler comprising a receptacle, a bail including side bars having a pivotal connection with said receptacle, a closure mounted for free sliding movement between said side bars, said closure engaging the bars whereby it is maintained at right angles to the bars, and a bottle support mounted on said closure.

2, A cooler comprising a receptacle, abail including side bars which are pivotally connected to the receptacle, a closure for the receptacle consisting of a disk said disk being notched at diametrically opposite points to receive the side bars of the bail whereby the disk is supported for a free sliding movement longitudinally of said bars and maintained at right angles to the bars, and a bottle support carried by the disk.

3. A cooler comprising a receptacle, a bail formed of wire and including side bars which at their terminals are pivotally con nected to the receptacle, a closure fort-he receptacle consisting of a disk provided at diametrically opposite points with notches which receive said bars whereby the disk is normally maintained at right angles to the bars, and a bottle support carried by said disk.

4. A cooler including a'receptacle formed of fabric, a ring embracing the receptacle at its open end'and maintaining the same extended, a bail including side bars the terminals of which project through the side of the receptacle and engage beneath the ring, and a closure for the receptacle carried by said bail. i

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
